Command Syntax
A command is one or more words that might be followed by one or more parameters.
Parameters can be required or optional values.
Some commands, such as show network or clear vlan, do not require parameters.
Other commands, such as network parms, require that you supply a value after the
command. You must type the parameter values in a specific order, and optional parameters
follow required parameters. The following example describes the network parms
command syntax:
Format network parms <ipaddr> <netmask> [gateway]
• network parms is the command name.
• <ipaddr> and <netmask> are parameters and represent required values that you
must enter after you type the command keywords.
• [gateway] is an optional parameter, so you are not required to enter a value in place of
the parameter.
The New Template User Manual lists each command by the command name and provides a
brief description of the command. Each command reference also contains the following
information:
• Format shows the command keywords and the required and optional parameters.
• Mode identifies the command mode you must be in to access the command.
• Default shows the default value, if any, of a configurable setting on the device.
The show commands also contain a description of the information that the command shows.
Command Conventions
In this document, the command name is in bold font. Parameters are in italic font. Y ou
must replace the parameter name with an appropriate value, which might be a name or
number. Parameters are order-dependent.

The parameters for a command might include mandatory values, optional values, or keyword
choices. Table 1 describes the conventions this document uses to distinguish between value
types.

Common Parameter Values
Parameter values might be names (strings) or numbers. To use spaces as part of a name
parameter, enclose the name value in double quotes. For example, the expression “System
Name with Spaces” forces the system to accept the spaces. Empty strings (““) are not valid
user-defined strings. Table 2 describes common parameter values and value formatting.
Table 2. Parameter Descriptions
ParameterDescription
ipaddrThis parameter is a valid IP address. You can enter the IP address in the following formats:
In addition to these formats, the CLI accepts decimal, hexadecimal, and octal formats
through the following input formats (where n is any valid hexadecimal, octal, or decimal
number):
0xn (CLI assumes hexadecimal format)
0n (CLI assumes octal format with leading zeros)
n (CLI assumes decimal format)

Table 2. Parameter Descriptions (Continued)
ParameterDescription
Logical InterfaceRepresents a logical slot and port number. This is applicable in the case of a port-channel
(LAG). You can use the logical slot/port to configure the port-channel.
Character stringsUse double quotation marks to identify character strings, for example, “System Name with
Spaces”. An empty string (“”) is not valid.
Slot/Port Naming Convention
Managed switch software references physical entities such as cards and ports by using a
slot/port naming convention. The software also uses this convention to identify certain logical
entities, such as Port-Channel interfaces.
The slot number has two uses. In the case of physical ports, it identifies the card containing
the ports. In the case of logical and CPU ports it also identifies the type of interface or port.
Table 3. Type of Slots
Slot TypeDescription
Physical slot numbers Physical slot numbers begin with zero, and are allocated up to the maximum
number of physical slots.
Logical slot numbers Logical slots immediately follow physical slots and identify port-channel (LAG) or
router interfaces.
CPU slot numbersThe CPU slots immediately follow the logical slots.
The port identifies the specific physical port or logical interface being managed on a given
slot.
Table 4. Type of Ports
Port TypeDescription
Physical PortsThe physical ports for each slot are numbered sequentially starting from zero.
Logical InterfacesPort-channel or link aggregation group (LAG) interfaces are logical interfaces that
are only used for bridging functions.
VLAN routing interfaces are only used for routing functions.
Loopback interfaces are logical interfaces that are always up.
Tunnel interfaces are logical point-to-point links that carry encapsulated packets.
CPU portsCPU ports are handled by the driver as one or more physical entities located on
physical slots.
Using the Command-Line Interface
11
ProSafe M4100 and M7100 Managed Switches
Note: In the CLI, loopback and tunnel interfaces do not use the slot/port
format. To specify a loopback interface, you use the loopback ID. To
specify a tunnel interface, you use the tunnel ID.
Using a Command’s “No” Form
The no keyword is a specific form of an existing command and does not represent a new or
distinct command. Almost every configuration command has a no form. In general, use the
no form to reverse the action of a command or reset a value back to the default. For example,
the no shutdown configuration command reverses the shutdown of an interface. Use the
command without the keyword no to reenable a disabled feature or to enable a feature that
is disabled by default. Only the configuration commands are available in the no form.
Managed Switch Modules
Managed switch software consists of flexible modules that can be applied in various
combinations to develop advanced Layer 2/3/4+ products. The commands and command
modes available on your switch depend on the installed modules. Additionally, for some show
commands, the output fields might change based on the modules included in the software.
The software suite includes the following modules:
• Switching (Layer 2)
• Routing (Layer 3)
• IPv6—IPv6 routing
• Multicast
• Quality of Service
• Management (CLI, web UI, and SNMP)
• IPv6 Management—Allows management of the device through an IPv6 through an IPv6
address without requiring the IPv6 Routing package in the system. The management
address can be associated with the network port (front-panel switch ports) and a routine
interface (port or VLAN).
• Stacking
Not all modules are available for all platforms or software releases.
Command Modes
The CLI groups commands into modes according to the command function. Each of the
command modes supports specific software commands. The commands in one mode are not
available until you switch to that particular mode, except for the User EXEC mode
Using the Command-Line Interface
12
ProSafe M4100 and M7100 Managed Switches
commands. You can execute the User EXEC mode commands in the Privileged EXEC
mode.
The command prompt changes in each command mode to help you identify the current
mode.
Table 5 describes the command modes and the prompts visible in that mode.
Note: The command modes available on your switch depend on the
software modules that are installed. For example, a switch that does
not support BGPv4 does not have the Router BGPv4 Command
Mode.

Accessing the CLI
You can access the CLI by using a direct console connection or by using a telnet or SSH
connection from a remote management host.
For the initial connection, you must use a direct connection to the console port. You cannot
access the system remotely until the system has an IP address, subnet mask, and default
gateway. You can set the network configuration information manually, or you can configure
the system to accept these settings from a BOOTP or DHCP server on your network. For
more information, see
Network Interface Commands on page 626.

that ingress or egress the interface. You can use the mtu command to configure jumbo frame
support for physical and port-channel (LAG) interfaces. For the standard 7000 series
implementation, the MTU size is a valid integer between 1522–9216 for tagged packets and
a valid integer between 1518–9216 for untagged packets.
Note: To receive and process packets, the Ethernet MTU must include
any extra bytes that Layer-2 headers might require. To configure the

Loopback Interface Commands
The commands in this section describe how to create, delete, and manage loopback
interfaces. A loopback interface is always expected to be up. This interface can provide the
source address for sent packets and can receive both local and remote packets. The
loopback interface is typically used by routing protocols.
To assign an IP address to the loopback interface, see ip address on page 228. To assign an
IPv6 address to the loopback interface, see ipv6 address on page 359.

Voice VLAN Commands
This section describes the commands you use for Voice VLAN. Voice VLAN enables switch
ports to carry voice traffic with defined priority to enable separation of voice and data traffic
coming onto the port. The benefits of using V oice VLAN is to ensure that the sound quality of
an IP phone could be safeguarded from deteriorating when the data traffic on the port is high.
Also the inherent isolation provided by VLANs ensures that inter-VLAN traffic is under
management control and that network- attached clients cannot initiate a direct attack on
voice components. QoS-based on IEEE 802.1P Class of Service (CoS) uses classification

Private VLAN
The Private VLANs feature separates a regular VLAN domain into two or more subdomains.
Each subdomain is defined (represented) by a primary VLAN and a secondary VLAN. The
primary VLAN ID is the same for all subdomains that belong to a private VLAN. The
secondary VLAN ID differentiates subdomains from each other and provides Layer 2 isolation
between ports of the same private VLAN. The types of VLANs within a private VLAN are as
follows:
• Primary VLAN—Forwards the traf
fic from the promiscuous ports to isolated ports,
community ports, and other promiscuous ports in the same private VLAN. Only one
primary VLAN can be configured per private VLAN. All ports within a private VLAN share
primary VLAN.
• Isolated VLAN—A secondary VLAN that carries traf
fic from isolated ports to promiscuous
ports. Only one isolated VLAN can be configured per private VLAN.
• Community VLAN—A secondary VLAN that forwards traf
fic between ports that belong to
the same community and the promiscuous ports. There can be multiple community
VLANs per private VLAN.
Three types of port designations exist within a private VLAN:
• Promiscuous Ports—An endpoint connected to a promiscuous port is allowed to
communicate with any endpoint within the private VLAN. Multiple promiscuous ports can
be defined for a single private VLAN domain.
• Isolated Ports—An endpoint connected to an isolated port is allowed to communicate with
endpoints connected to promiscuous ports only
. Endpoints connected to adjacent
isolated ports cannot communicate with each other.
• Community Ports—An endpoint connected to a community port is allowed to
communicate with the endpoints within a community and with any configured
promiscuous port.
The endpoints that belong to one community cannot communicate with
endpoints that belong to a different community or with endpoints connected to isolated
ports.
The Private VLANs can be extended across multiple switches through inter-switch/stack links
that transport primary
, community, and isolated VLANs between devices.

GARP Commands
This section describes the commands you use to configure Generic Attribute Registration
Protocol (GARP) and view GARP status. The commands in this section affect both GARP
VLAN Registration Protocol (GVRP) and Garp Multicast Registration Protocol (GMRP).
GARP is a protocol that allows client stations to register with the switch for membership in
VLANS (by using GVMP) or multicast groups (by using GVMP).
set garp timer join
This command sets the GVRP join time for one port (Interface Config mode) or all (Global
Config mode) and per GARP. Join time is the interval between the transmission of GARP
Protocol Data Units (PDUs) registering (or re-registering) membership for a VLAN or
multicast group. This command has an effect only when GVRP is enabled. The time is from
10 to 100 (centiseconds). The value 20 centiseconds is 0.2 seconds.

set garp timer leave
This command sets the GVRP leave time for one port (Interface Config mode) or all ports
(Global Config mode) and only has an effect when GVRP is enabled. Leave time is the time
to wait after receiving an unregister request for a VLAN or a multicast group before deleting
the VLAN entry . This can be considered a buffer time for another station to assert registration
for the same attribute in order to maintain uninterrupted service. The leave time is 20–600

Storm-Control Commands
This section describes commands you use to configure storm-control and view storm-control
configuration information. A traffic storm is a condition that occurs when incoming packets
flood the LAN, which creates performance degradation in the network. The Storm-Control
feature protects against this condition.
The 7000 series provides broadcast, multicast, and unicast story recovery for individual
interfaces. Unicast Storm-Control protects against traf
fic whose MAC addresses are not
known by the system. For broadcast, multicast, and unicast storm-control, if the rate of traffic
ingressing on an interface increases beyond the configured threshold for that type, the traffic
is dropped.
To configure storm-control, you will enable the feature for all interfaces or for individual
interfaces, and you will set the threshold (storm-control level) beyond which the broadcast,
multicast, or unicast traf
fic will be dropped. The Storm-Control feature allows you to limit the
rate of specific types of packets through the switch on a per-port, per-type, basis.
Configuring a storm-control level also enables that form of storm-control. Disabling a
storm-control level (using the “no” version of the command) sets the storm-control level back
to the default value and disables that form of storm-control. Using the “no” version of the
“storm-control” command (not stating a “level”) disables that form of storm-control but
maintains the configured “level” (to be active the next time that form of storm-control is
enabled.)
Note: The actual rate of ingress traf fic required to activate storm-control is
based on the size of incoming packets and the hard-coded average
packet size of 512 bytes - used to calculate a packet-per-second
(pps) rate - as the forwarding-plane requires pps versus an absolute
Switching Commands

ProSafe M4100 and M7100 Managed Switches
rate kbps. For example, if the configured limit is 10%, this is
converted to ~25000 pps, and this pps limit is set in forwarding plane
(hardware). You get the approximate desired output when 512bytes
packets are used.
storm-control broadcast
Use this command to enable broadcast storm recovery mode for a specific interface. If the
mode is enabled, broadcast storm recovery is active and, if the rate of L2 broadcast traffic
